Knowing exactly what’s in your water means that you know the exact total water hardness and iron content before you start your research. I cannot begin to tell you how many calls I receive from potential customers that want to purchase a salt free conditioner and when I ask them how hard the water is, their answer is “Its real hard”. What is “real hard”? Hard water is defined as water more than three grains hard. While most well water and municipal water will test between ten grains and twenty five grains, some water will test much higher, as much as ninety grains and even higher. While I hate to admit it, there are applications where a Salt Free Water Conditioner may not be a good fit. These applications are usually where water exceeds thirty five grains per gallon, and where sulfates are extremely high. High levels of iron can also be an issue. Nearly every call I receive from customers who have already purchased a conditioner from another company, and are not happy with its performance, were never asked what their water hardness was. How could that salesperson know which conditioner would treat that customers water if they did not know how hard the water was? The answer to that question is this; not everyone qualifies as a good fit for a Salt Free Water Conditioner, and not all conditioners are the same. This is why we offer several different conditioners, some treat harder water than others, and all have different features including cost, performance, and installation differences. And as I pointed out earlier, there are some applications where the water is just too hard to use a salt free conditioner in. In these cases I have to tell the customer that they need a conventional salt based water softener. But I would rather be honest than to deal with a customer that is not happy with the product they purchased from me. So before you begin, find out your water hardness. This can be done several ways without spending too much money. If you need to, you can mail us a sample and we test water for free at our office. Details are on our website HERE.
